car radar?

LADAR (LAser Detection And Ranging) calculates a vehicle's speed in milliseconds, just because you detected a laser signal does not mean the laser was pointed at you or the officer wanted to chase you but can't read your speed in time.

Most laser detection occurs from reflections off another vehicle in your line of sight that the officer is targeting so he doesn't care what speed you were going since you were not the target making the detection worthless.

If the LADAR is being used right (waiting 30-60sec between uses) and you are the target you will never know until it is too late because the chances of picking up a line of sight reflection over a mile away is slim.

Same issue with instant on/off Radar guns, but it is nearly impossible for a radar run to function properly if there are more then 2 cars near you. Its a system limitation. Hence why they use Lasers more often in high density areas.
